Timgad spread beyond the perimeters of its ramparts and several major public buildings are built in the new quarters: Capitolium, temples, markets and baths. A strong and prosperous colony, Timgad must have served as a compelling image of the grandeur of Rome on Numidian soil. After the Vandal invasion of 430, Timgad was destroyed at the end of the 5th century by montagnards of the Aurès. Criterion (iii): Timgad adopts the guidelines of Roman town-planning governed by a remarkable grid system. The Ministry of Culture relocated the activities related to the Annual Festival of Timgad outside the site.
